launch-k6nele-on-things.sh

#!/bin/sh

# Example of launching Kõnele using 'adb shell am' optimized for Android Things.
# First set up Android Things on a Raspberry Pi3 so that you can access it via adb
# by "adb connect Android.local",
# see https://developer.android.com/things/hardware/raspberrypi.html
#
# Setting up Kõnele on the device:
# 1. adb uninstall ee.ioc.phon.android.speak (if old version is installed)
#    adb install /path/to/K6nele-x.y.zz.apk
#      adb shell pm grant ee.ioc.phon.android.speak android.permission.RECORD_AUDIO (granting permissions)
#      or: adb reboot (this grants the permissions)
#    or: adb install -r -g /path/to/K6nele-x.y.zz.apk (reinstall and grant permissions, no reboot needed)
# 2. Import some rewrite rules from a URL
#    Current solution: use adb to write a rewrites table into the local storage
#    adb-pref.sh keyRewritesMap/Hue -e val "https://docs.google.com/spreadsheets/d/1x8FkaMoJ4_gJbg6w1vhir0gkWmqHuXDiB7otNr56Yb4/export?format=tsv" --ez is_url true
# 3. TODO: remove "Tap&Speak" + mic button (which do not make sense for a notouch device)
#    (using adb to modify the preferences + extending Kõnele not to refer to touch in the UI)
#    adb-pref.sh keyHelpText --ez val false
# 4. ...
# .. Look at some settings: adb shell am start -a android.settings.VOICE_INPUT_SETTINGS
# .. adb shell am start -a com.android.settings.TTS_SETTINGS
# .. press BACK: adb shell input keyevent 4
# .. adb shell 'pm list packages'
#
# Usage:
# 1. Launch this script, i.e. launch-k6nele-on-things.sh
# 2. Speak the name of a song/artist into the device
# 3. (TODO) Some music player on the device starts playing the given song/artist
# Note that the service/locale must be among the selected combos, or the default combo.
#
# Shutdown:
#
# adb shell reboot -p
